                Hold the mustard: A zesty relish of almond, cilantro, jalapeño, lime juice, and garlic makes a much more interesting spread. Pack these sandwiches next to an ice pack to keep them cool and fresh as you travel to the picnic.

Bring water to a simmer in a 4- to 5-quart pot, then add chicken and simmer, uncovered, 6 minutes. Remove pan from heat and let stand, covered, until chicken is cooked through, about 15 minutes. Transfer chicken to a plate and cool completely, then cut diagonally into thin slices.
                                         
                                    
                                
                             
                        
                            
                                Roast bell peppers:
                                
                                
                                    
                                        - 
                                            
                                            
Roast bell peppers on racks of gas burners over high heat, turning with tongs, until skins are blackened, 10 to 12 minutes. (Or broil peppers on rack of a broiler pan about 5 inches from heat, turning occasionally, about 15 minutes.) Transfer to a large bowl and cover tightly with plastic wrap, then let stand 20 minutes.

 When cool enough to handle, peel peppers, discarding stems and seeds, and cut lengthwise into 1 1/2-inch-wide strips.

While peppers are standing, pulse almonds, garlic, and jalapeño in a food processor until finely chopped. Add cilantro, mayonnaise, lime juice, sour cream, and salt and blend to a paste.

Spread cilantro relish on each slice of bread, then make sandwiches with chicken and roasted peppers, seasoning with salt and pepper.
                                         
                                    
                                
                             
                        
                    
                    Cooks’ notes: - Chicken can be poached (but not sliced) 1 day ahead and chilled, covered.
  - Bell peppers can be roasted, peeled, and sliced 1 day ahead and chilled, covered.
  - Relish can be made 1 day ahead and chilled, its surface covered with plastic wrap.
